Its really fun, keeps you interested when you add a node and instantly see what it does. And it definitely makes certain things even possible. Like distributing objects in a pattern then distorting said pattern and have all the objects react to the distortion. Just start messing with it, the only way to understand is to use it.
Excited for this and the future texturing tutorial. The platform I work with only uses baked-down lowpoly textures, but I'm sure this will still help a ton in getting there!
Bit of a niche request, but do you have any tricks for orientating a 3D tracking scene when the automatic tools just aren't cutting it? I always get annoying shots where there's nothing on the ground to track.
The normal direction just points in the face up or outside direction, Z - it does not really tell you anything about what is "left" and "right" of the cardboard or in other words X and Y. Also each face has its own normal, so you have no continuous left to right range to use a sine or cosine function.
@@gordonbrinkmann actually you can. you should modulo the indices by 2 and subtract their location to get their vector direction and then apply the offset according to normal. with modulo you can also make your own sine wave.
@@danialsoozani The problem is not the sine wave. The problem is, if you want to make some cardboard which is not perfectly straight and flat, the normals will still point in the faces' Z direction, but the X and Y direction can vary from face to face which could result in unwanted turns of that zigzag paper.
@@gordonbrinkmann I know what you mean, but I think you didn't realize what I meant. maybe I make a video about it later but I'll tell you in short if you get it through this text, you can zero out the unwanted directions by using the direction of indices regardless of problems you mentioned above. you can watch Erindale to get what i mean.
I still havent really hopped on the GoeNode train and every one of your tutorials convinces me that I should really start with it 😅

I don't need it, but I watch. Why? Because it's super dense valuable information, it's pure gold!
What he said
Such a big brain move to use the UV Maps to calculate the direction of the corrugation. Nice one!
WOAH! You posed an amazing use case for UV maps here!
I am convinced of the geonode powers.
God I love cardboard
gerat idea to use the uv coordinates :)
This is quite great! Though I wonder if there is a way to do this without hurting the initial geometry of the object...

Dude really awesome 👏 tutorial. 😊 love the music 😁
thank ya! very nice of you
@@CGMatter is a pleasure, you are the GURU of Blender 😁😄😃
I'm loving these speed run tutorials. It like a mind dump of knowledge that my hummingbird mind can slurp up.
Brilliant
This is great
I hope you're okay and making some new plans for adventures or other strives within your life.
id kill for the texturing tutorial i've needed this like 5 times over in the last few projects. guess its time to geometry node
👑
Great tut, thanks! Is there any way to avoid handmade subdivisions and make it procedural?
Not something obvious I can think of - a loop cut kind of node would be great
dope 🤙
Except cardboard doesn't bend smoothly... It kinks.

damn thanks!
Wow. I'll have to try out geometry nodes now...
now do this in shader nodes please 🙏
Nicely explained, can't we use procedural UV mapping though?
ya! as long as they're oriented correctly
very nice usage of UVmaps for deformation! I was thinking can't we use normal for the direction?

Or just take a picture of a cardboard box and project it
that would only solve the faces, not the interior "ridges"
